Explore Honolulu

Buildings along the coastline of Honolulu, Hawaii

Hawaii’s capital, Honolulu is located on Oahu’s south shore and is the state’s hub for business, culture, and entertainment. Highlights include the Honolulu Museum of Art, Bishop Museum, and the Chinatown district.

If you want to make the most of your time in the capital, join the Honolulu city tour that’ll take you to some must-see attractions including the Kawaiahaʻo Church, Pearl Harbor, and the USS Arizona.

Be sure to plan some time to explore Waikiki, the city’s most famous neighborhood which is known for its excellent surf and vibrant nightlife. There are plenty of things to do in Waikiki, including taking a surfing lesson on the main beach and visiting Iolani Palace before watching a traditional hula show or taking a sunset cruise.

Go surfing at North Shore

Situated about 30 minutes from Honolulu, the North Shore (yes, it’s located on the north shore of the island) is one of the best spots in Oahu for surfing. Note that the waves can get pretty big, so it’s definitely not ideal for beginners. Once you’ve had a few lessons, head to the North Shore to escape the crowds and cut some waves.

Swim at Hanauma Bay

Pristine sands and crystal-clear waters are what make Hanauma Bay stand out as one of the best spots for swimming and snorkeling on the island. Head there early to snag a parking place and a good spot on the beach.

Snorkeling in Oahu

Oahu is a sublime place to go for a swim and snorkeling. We put together a massive list of 22 of the very best spots to snorkel on the island. Check it out and pick the best spot for yourself!

Hike the Kaena Point trail

Just under 10km, the Kaena Point Trail is a moderate out-and-back trail near Waialua in Oahu. You can complete the walk in just over 2 hours.

Along the way you can enjoy coastal views and – if you’re lucky – you may even spot albatrosses, seals or whales. We recommend taking a few beers or a picnic dinner and heading up to catch the sunset. Just remember to take your trash back with you!

Visit Byodo-In Temple

The Hawaiian version of the original Byodo-In Temple in Uji Japan is located in the Valley of the Temples Memorial Park at the foot of the Ko’olau Mountains. Built to commemorate the 100th anniversary of the first Japanese immigrants to Hawaii, the temple is a must-see if you’re visiting Oahu. The Buddhist temple welcomes visitors to meditate, worship, or just appreciate its incredible beauty.

Turtle spotting at Laniakea Beach

Oahu isn’t short of beautiful beaches, but Laniakea Beach stands out because it’s a favorite spot for Hawaii’s green sea turtles to hang out. Head there to catch a glimpse of these creatures in their natural habitat, but be sure not to get too close as the turtles are protected under Hawaiian law.

It’s one of the coolest beaches in Hawaii, and totally deserves a visit! 

Hike to the volcanic crater at Diamond Head
